SYNTAX xx SN nn or xx SN ?
PARAMETERS
Description xx [ int ] - axis number
nn [ int ] - displacement units
Range
xx - 1 to MAX AXES
nn - 0 to 10 where
0 = encoder count 6 = micro-inches
1 = motor step 7 = degree
2 = millimeter 8 = gradient
3 = micrometer 9 = radian
4 = inches 10 = milliradian
5 = milli-inches 11 = microradian
or ? to read present setting
Units
xx - none
nn - none
Defaults
xx missing: error 37, AXIS NUMBER MISSING
out of range: error 9, AXIS NUMBER OUT OF RANGE
nn missing: error 38, COMMAND PARAMETER MISSING
out of range: error xx2, PARAMETER OUT OF RANGE
DESCRIPTION
This command is used to set the displacement units for the for axis xx .
Note:
The unit of measure as used with this controller is intended as a label only. It is
the user’s responsibility to convert and resend all affected parameters (e.g.,
velocity, acceleration, etc…) when switching from one unit of measure to
another.
RETURNS
If the “?” sign takes the place of nn value, this command reports the current
setting
REL. COMMANDS
FR - set full-step resolution
SU - set encoder resolution
EXAMPLE
2SN | read displacement unit setting of axis # 2
2 | controller returns a value 2 (millimeter) for axis #2
2SN 0 | set displacement unit to 0 (encoder count) for axis #2
